Infinity RS 2.5 speaker placement

Wow. I actually owned a pair of those years ago. Great speaker in their day...

I agree with Elizabeth. Start with them about four feet out from the front wall (wall behind the speakers).

BTW, they are not a dipolar design. They are a bipolar design having a rear firing EMIT tweeter in phase with the front firing EMIT. Anyway, they require tons of power to "wake up" so feed them lots of good, clean watts! Of all the speakers I have owned over the years, they were the most power hungry. And I own / have owned Magnepan and Apogee!

Be patient. Good luck.

They get about 450 watts a piece from an edge nl-10, so no current problems. I have them 5'2" to the center of the woofer from the back wall and laid out by the cardas formula. I will just have to fine tune it by ear. Thanks for the responses

I had a pair of 2.5's for quite a few years. I replaced their vintge tweeter & midrange capacitors with modern polypropleans.
They image better when not too far from rear wall due to rear tweeter; I had mine 41" (wall to front).
Lower bass was great, but upper bass was weak due to crossover design (an equalizer would benifit here).

Don't set them too far apart either.

Wings,

Did you notice a difference when recapping them? Probably not a cheap overhaul either, I imagine. I have the optional eq/crossover that came with these, but I have always left it out because the sound seemed to degrade slightly. Also, I have an audio rack against the wall that I'm sure is not helping things, but it's what I have for now.
I should say...on a good recording, the speakers are invisible as is, the stage goes from past the extreme left of the speaker to past the extreme right of the other speaker. The bass is tight and a huge improvement over where I had them positioned to start with which was about 2 ft. from the back wall and 1.5 ft. from the sides. At that position, the bass was so boomy, my tube phono preamp was picking it up at high volume. Part of the problem is that I'm experimenting with my listening position at the same time as speaker position.

In regards to upper bass, I noticed a big change when I got the Bryston preamp, and another large change going from an Adcom gfa-5500 to the edge nl-10. Something like James Taylor's Fire and Rain, the drum fills are right there like a trap set in front of you. I know these old monsters are far from the end all in speakers, especially these days, but for the price used, I haven't heard anything that compares.

In previous experiments with toe-in, I found that it narrowed the effective listening width in my situation, but that was in a different room too, so I will give it a shot just to see...
